The design + is presented as an extension of a privacy-friendly payment protocol with a + zero-knowledge scheme that cryprographically augments coins for this purpose. + Our scheme enables buyers to prove to be of sufficient age for a particular + transaction without disclosing it. Our modification preserves the privacy and + security properties of the payment system such as the anonymity of minors as + buyers as well as unlinkability of transactions. We show how our scheme can be + instantiated with ECDSA as well with a variant of EdDSA, respectively, and how + it can be integrated with the GNU Taler payment system. We provide formal + proofs and implementation of our proposal. Key performance measurements for + various CPU architectures and implementations are presented. +</p> +<h2>Download links</h2> +<ul> + <li><a href="/papers/esorics2022-age-restriction.pdf">PDF (English)</a></li> + <li><a href="/presentations/esorics2022.pdf">PDF of presentation on ESORICS 2022 (English)</a></li> + <li>The paper has been <a href="https://link.springer.com/chapter/10.1007/978-3-031-17140-6_6">published in the proceedings to ESORICS 2022</a></li> + +</ul> + +{% endblock body_content %} |
